They aim to share technical knowledge and expertise on clean energy, including smart grids, electric vehicles and carbon capture and storage.

The UK’s carbon emissions have fallen by more than a third since 1990, while the economy has grown by two-thirds – it will now assist Saudi Arabia in its plans to grow the country’s renewable technologies sector, improve its energy efficiency and diversify its energy mix.

Business Secretary Greg Clark said: “The global shift to clean growth is one of the most foreseeable and significant global economic trends and will transform many sectors of the economy, including power, transport, construction, energy-intensive industries and agriculture.

“This MoU will help both the UK and Saudi Arabia make the most of this shift.”
